Summary of the invention
Present invention mainly solves the technical issues of: for the common anti-bacterial fibre plate of current tradition mostly be using antimicrobial fluid soak
The mode of bubble fiberboard makes its surface adhere to antibacterial agent, but this mode can generate destruction to fiberboard mechanical property, and
Antibacterial agent is unstable in conjunction with fiberboard, is easy to fall off the defect for making anti-microbial property be deteriorated, and the present invention is obtained by digesting alcohol extracting
Licoflavone extracting solution, then bamboo flax silk fiber is extracted from thin bamboo strips used for weaving, first bamboo flax silk fiber surface is carried out with pig manure and methane liquid
Micro- rotten processing makes bamboo flax silk fiber surface be covered with micropore, then impregnates micro- bean curd stick flax silk fiber with liquor alumini chloridi, keeps aluminium chloride negative
It is loaded in bamboo flax silk fiber surface and its micropore, then the bamboo flax silk fiber for loading aluminium chloride is immersed into licoflavone extracting solution, benefit
Licoflavone is complexed with aluminium chloride, is attached to it closely in fiber surface and its hole, anti-bacterial fibre is made, it finally will be fine
Hot pressing is after dimension sizing up to anti-bacterial fibre plate, and the present invention is made fiberboard and is not required to be impregnated using antimicrobial fluid, and fiber itself has anti-
Bacterium property, and antimicrobial component is firmly combined with fiber, will not fall off, fiberboard mechanical property itself is splendid, has wide application
Prospect.
